Determine Your Certificate Transparency

You can also check for Certificate Transparency in the certificate details. If you are using certificates issued before October 1, 2017, you may need to upgrade, replace or reissue your certificate. If your website is not CT-compliant with logged certificates, users may see warnings in Google Chrome.

If you want to hide the details of your private website, choose 'Root domain names only' when enrolling new certificates. This is covered by the latest version of the Internet Engineering Task Force (IETF) standards but may not be respected by all browsers or Certificate Transparency logs.

Protect Your Digital Brand

Now it's easier for browsers to spot phishing sites and fake certificates, strengthening trust.

Spot Certificate / Identity Issues

Reveal improperly issued certificates by cross-checking them against public logs.

Full DigiCert Support

All DigiCert certificates include CT, and our tools and certificate issuance processes make it easy to support.

Maintain Privacy

DigiCert supports emerging standards to protect the details of internal, private and sensitive domains.

Easy and Simple to Deploy

CT is automatically included in any certificates issued after October 1, 2017, and it's easy to update older certificates.

Increased Trust Online

CT makes it harder for hackers and criminals to weaken consumer trust in SSL/TLS certificates.

TRUST AND VERIFY

DigiCert is leading the industry in support of Certificate Transparency.

CT is standard in all our SSL/TLS certificates. It works like this: Certificate Authorities, such as DigiCert, log new certificates in publicly accessible, tamper-proof registries. Browsers can use these logs to verify certificates, and IT managers can also use them to spot problems, including improperly issued, out-of-policy and rogue certificates.

Check Certificate Transparency for Your Site

Use DigiCert's CryptoReport to look up your domain in public logs, including DigiCert's.
